I went with the tarragon option and used almost double the amount because we really love it. By itself this sauce didn't do much for me but it sang when paired w/the salmon cakes. They complement each other beautifully.

I made this sauce to go with the Deviled Salmon Cakes, and used mint. The cakes were delicious, however the sauce was not good at all. So I divided the sauce in half, and added equal amounts of mayo, which made it taste just ok.
